Jonathan Halliday commented on JBTM-932:

You don't need recovery by the parent. The subordinate can legitimately make an autonomous rollback decision under the 'presumed abort' rule. Normally that is via the tx reaper timing out the subordinate tx.

> The call to XATerminator::recover() only returns transactions that are in the RecoveryStore.
> What if?
> 1. EIS propagates transaction "XYZ"
> 2. EIS crashes
> 3. We are not notified of this
> 4. EIS recovers
> 5. EIS calls XATerminator::recover
> 6. The inflight "XYZ" is not returned as it was not prepared and is therefore not in the RecoveryStore
